In practice, the pushing part 200 may take various forms, for example, detection is performed by a temperature sensor, and the movement of the electronic control board 70 is pushed by the driving lever according to the detection result. The form in which the pushing part 200 includes the first magnet 210, the second magnet 220, and the elastic member 230 is provided in the present embodiment, but the scope of protection should not be limited to the following embodiments.
As shown in fig. 2 and 3, the first magnet 210 is disposed on the electric control board 70, the second magnet 220 is disposed on the mounting portion 100, the elastic member 230 is disposed between the electric control board 70 and the mounting portion 100, the first magnet 210 and the second magnet 220 attract each other, and the adsorption force between the first magnet 210 and the second magnet 220 is affected by the temperature of the electric control board 70. By adopting the first magnet 210 and the second magnet, the adsorption force of which is affected by temperature, the electric control plate 70 can automatically move relative to the air inlet of the fan 40 according to the temperature. The mode is simple and reliable in structure and convenient to realize.
In particular, as shown in fig. 2, in an initial state, the electronic control board 70 may be in an initial position in which the electronic control board 70 is closer to the mounting portion 100, and the receiving chamber of the mounting portion 100 can protect the electronic control board 70. As shown in fig. 3, when the temperature of the electric control board 70 exceeds a preset value, the adsorption force between the first magnet 210 and the second magnet 220 is reduced, the elastic member 230 applies a force to the electric control board 70 to move in a direction approaching the blower 40, and the electric control board 70 moves in a direction approaching the blower 40. Thereby enabling the electric control board 70 to perform sufficient heat convection and improving the cooling effect. The preset value may be configured according to actual situations, so that the pushing portion 200 can timely push the electric control board 70 to cool.
When the fan 40 stops rotating, the water heater 1 is in a non-running state, the water heater 1 is not heated, the water temperature in the water pipe is reduced, as shown in fig. 1, a water outlet pipe 60 is arranged between the fan 40 and the electric control plate 70, hot air encounters the colder water outlet pipe 60, water drops are easy to condense, the larger the humidity is, the more water drops are dropped into the electric control plate 70, and the electric control plate 70 is required to be reset.

As shown in fig. 5, the pushing part 200 further includes a magnetizing unit 240, and the magnetizing unit 240 is electrically connected to at least one of the first magnet 210 and the second magnet 220 and serves to magnetize at least one of the first magnet 210 and the second magnet 220.
Specifically, when the blower fan 40 stops rotating, the magnetizing unit 240 magnetizes at least one of the first magnet 210 and the second magnet 220, the attraction force between the first magnet 210 and the second magnet increases, and the electronic control board 70 moves in a direction away from the blower fan 40. When the fan 40 stops rotating and is in a non-operation state, the magnetizing unit 240 can timely charge the magnet, so that the electric control board 70 is far away from the fan 40, and the short circuit caused by the dripping of condensed water is avoided. As shown in fig. 2 and 3, when the water heater 1 is in an operation state and the electric control board 70 needs to be cooled, the electric control board 70 moves from the initial position of fig. 2to the position of fig. 3, and when the water heater 1 is in a non-operation state, through the magnetizing mode, the adsorption force between the two magnets is recovered, so that the electric control board 70 can be recovered from the position of fig. 3to the position of fig. 2, and the electric control board 70 can be protected.
In practice, the magnetizing unit 240 may magnetize one or both of the first magnet 210 and the second magnet 220 according to the need, thereby restoring the attraction force therebetween. The particular choice may be affected by the choice of materials for the first magnet 210 and the second magnet 220. Preferably, the magnetizing unit 240 is electrically connected to the first magnet 210 and serves to magnetize the first magnet 210. The magnetizing unit 240 can be powered by a circuit on the electronic control board 70, and the first magnet 210 is also disposed on the magnetizing unit 240, so as to facilitate the arrangement and implementation of components.
As a specific embodiment of the magnetizing unit 240, as shown in fig. 5, the magnetizing unit 240 includes a power source 241, a coil (not shown) and a diode 242, the coil is wound around the first magnet 210, the power source 241, the coil and the diode 242 are connected in series, and when the fan 40 stops rotating, the diode 242 is turned on, and the power source 241 supplies power to the coil.
In a specific implementation, the power source 241 may output a current using the electronic control board 70, in particular, the electronic control board 70 may output a forward current, as shown by an arrow I in fig. 5, and when the electronic control board 70 outputs the forward current, the diode 242 is turned on, so that the coil magnetizes the first magnet 210. The electronic control board 70 may also output a reverse current in the opposite direction to the forward current, and when the reverse current is in the loop, the diode is turned off, the circuit is opened, and the coil is free of current.
Further, as shown in fig. 2 and 3, the heat dissipation assembly 80 further includes a contact switch 300, the contact switch 300 is disposed on the mounting portion 100, and when the electric control board 70 moves away from the fan 40 to contact with the contact switch 300, the power source 241 stops supplying power to the coil, and the magnetizing unit 240 stops magnetizing. The magnetizing unit 240 can stop magnetizing by the contact switch 300, thereby effectively controlling the magnetizing operation. Specifically, a plurality of contact switches 300 are provided at intervals on the upper and lower sides of the mounting part 100, thereby improving the accuracy of detection.
As one embodiment of the magnets, the first magnet 210 is a series N of neodymium-iron-boron magnets, the second magnet 220 is a series UH of neodymium-iron-boron magnets, and/or the resilient member 230 is a spring. The first magnet 210 is a low coercivity NdFeB N-series magnet which is easily demagnetized and demagnetizes at about 80 ℃ due to the temperature rise, and the second magnet 220 is a high coercivity NdFeB UH-system magnet which reduces at about 180 ℃. So that when the temperature of the electric control plate 70 is too high, the adsorption force between the two magnets is reduced, so that the electric control plate 70 moves toward the blower 40.
In the specific implementation, as shown in fig. 2, the neodymium-iron-boron N series magnet and the neodymium-iron-boron UH system magnet are in opposite attraction states, and the spring is in a compressed state. When the water heater 1 burns under a large load, the heat of combustion radiation is in the machine, and components on the electric control board 70 are heated to run, so that the temperature on the electric control board 70 is increased. Experimental tests the temperature of the electric control board 70 was about 85 deg.c under full load operation of the electric control board 70. The NdFeB-N series magnet has the property of low coercivity and is easy to demagnetize, the magnetism is demagnetized due to the temperature rise at about 80 ℃, and the NdFeB-UH series magnet has the property of high coercivity and the magnetism is weakened at about 180 ℃. As the temperature increases, the magnetic properties of the first magnet 210 decrease and the attraction force between the second magnet 220 decreases, and the spring overcomes the attraction force between the magnets to move the electric control board 70 toward the air inlet of the fan 40. The closer the electric control plate 70 is to the opening of the blower 40, the stronger the air convection, the faster the heat dissipation speed, and the temperature of the electric control plate 70 is raised and lowered. Therefore, the distance between the electric control plate 70 and the opening of the fan 40 is reduced by automatically adjusting the spring through weakening the magnetism of the magnet by the environment high temperature, and the aim of cooling is fulfilled by fully carrying out heat convection on the electric control plate 70.
In a specific implementation, the first magnet 210 is disposed on the electric control board 70, the magnetizing unit 240 may also be integrated on the electric control board 70, and the program carried on the electric control board 70 may also be used to determine whether the water heater 1 is in a non-operating state, so as to control the magnetizing unit 240 to magnetize the first magnet 210 when the water heater 1 is in the non-operating state, so that the adsorption force between the first magnet 210 and the second magnet 220 is recovered to overcome the spring force, and the electric control board 70 is reset.
As shown in fig. 5 and 6, the fan 40 stops rotating, and the electric control board 70 program determines that the water heater 1 is in a non-operating state, and at this time, the first magnet 210 is demagnetized at a high temperature, and the magnetism is irreversibly recovered after the temperature is lowered, so that the first magnet 210 needs to be magnetized. The coil is wound outside the first magnet 210, the electric control board 70 outputs current to magnetize the first magnet 210, the first magnet 210 is magnetically recovered, the attraction force is increased to overcome the elastic force of the spring, the electric control board 70 is pushed to a direction away from the fan 40, the electric control board 70 is away from the water outlet pipe 60, and the risk of short circuit is avoided. After the electric control board 70 is reset, the electric control board 70 contacts with the contact switch 300 on the mounting part 100, the program of the electric control board 70 receives the reset signal, the coil current output is stopped, and the magnetizing is completed.
